When you hit connect in XS++,press C button on phone and than connect USB cable - if that don't work - try to change USB port and clean conector on phone - if that don't work try to reinstall flash drivers

It's doesn't matter what tool you use - you must finalize flashing with CUSTPACK, but CUSTPACK must be same region like FS (so if you use FS - EUROPE_2 - than CUSTPACK must be for EUROPE_2). Just look here XS++ 3.1 Guide-Flashing, Customizing, Recovering - Top Sony Forums SECTION 4
